Klipsch R40SA Black

Klipsch R-40SA Dolby Atmos Elevation Speakers — Overhead Sound Without Ceiling Cutouts

The Klipsch R-40SA Dolby Atmos Surround Sound Speakers deliver immersive overhead audio by firing sound upward toward the ceiling, where it reflects back down to the listening position. Each speaker pairs a 1" LTS aluminum tweeter with a 90° x 90° Tractrix horn and a 4" spun-copper Thermoformed Crystalline Polymer (TCP) woofer. Sold as a matched pair in a textured black MDF cabinet, this model is engineered to sit on top of floorstanding monitors or function as a rear surround, adding a hemisphere of detailed sound to a home theater.

What Sets These Atmos Modules Apart

The R-40SA inherits its cone geometry from Klipsch's Reference Premiere line, with steeper TCP cone angling and additional ribbing that reduces breakup at higher frequencies. Integrated wire management routes the Atmos jumper cable through the cabinet so no cable is visible from the listening position, while hidden fasteners and low-profile magnetic grilles preserve a clean, modern appearance.

Horn-Loaded Tweeter for Controlled Directivity

The horn-loaded high-frequency section is the heart of any Klipsch speaker, and this model uses the same 1" LTS aluminum tweeter with Kapton suspension found across the Reference series. The 90° x 90° Tractrix geometry focuses energy toward the listening area, sharpening dialogue intelligibility and Atmos effect placement.

• Tweeter: 1" (25 mm) aluminum LTS with Kapton suspension — minimizes distortion for clean, detailed highs
• Horn Geometry: 90° x 90° Tractrix — controls directivity across a wider frequency band for a more accurate soundstage
• Crossover: 4.4 kHz — separates tweeter and woofer duties for coherent Atmos delivery

TCP Woofer and Reinforced MDF Cabinet

The 4" woofer uses Klipsch's spun-copper Thermoformed Crystalline Polymer cone, a material trickled down from the Reference Premiere series. The acoustic-suspension MDF cabinet is reinforced with internal bracing to reduce coloration, and the textured wood-grain vinyl resists scratches in everyday living-room use.

• Woofer: 4" (102 mm) spun-copper TCP — steeper cone angle improves accuracy and transparency
• Enclosure: Acoustic suspension, reinforced 3/4" MDF — reduces cabinet vibration for cleaner midrange
• Textured black wood-grain vinyl finish — scratch-resistant and décor-friendly

Power Handling and Connectivity

Each enclosure handles 50 W RMS and peaks at 100 W, with an 8 Ohm nominal impedance that pairs comfortably with most home-theater AVRs. A single set of gold-plated binding posts accepts bare wire, banana plugs, or the included right-angle adapters for tight installations atop floorstanding speakers.

• Power Handling: 50 W RMS / 100 W peak — comfortable headroom for Atmos effects
• Impedance: 8 Ohm — broad AVR compatibility
• Sensitivity: 85 dB — efficient output for typical home-theater amplifiers
• Single gold-plated binding posts — accept bare wire, banana plugs, or the included right-angle adapters

Ideal for Home-Theater Builders Adding Atmos Channels

The Klipsch R-40SA is the right choice for home-theater enthusiasts who want genuine Dolby Atmos overhead effects without cutting holes in the ceiling. Place them atop floorstanding speakers such as the Klipsch R-800F or R-600F, or use them as rear surrounds in a 5.1.4 or 7.1.4 layout. The included jumper wires and right-angle banana adapters make the physical install straightforward, while the textured black finish blends into most living-room décors. Owners of existing Reference-series speakers will appreciate the tonal continuity between these Atmos modules and the rest of the Klipsch lineup.

Klipsch Reference Series — Horn-Loaded Heritage Since 1946

This model belongs to the next-generation Klipsch Reference series, a line that traces its lineage to founder Paul W. Klipsch and his pioneering horn-loaded speaker designs. Klipsch's exclusive Tractrix horn geometry and LTS aluminum tweeter assembly have remained hallmarks of the brand for decades, and the R-40SA carries that tradition into the modern Atmos era with trickle-down Reference Premiere technology.
